To all whom, it may concern.-

Be it known that I, JosEPH A. HALEY, a citizen of the United States ofAmerica, residing at Fort \Vayne, in the county of Allen and State ofIndiana, have invented certain new and useful Improvements in Dust-Guards for Journal-Boxes or Lubricating- Receptacles; and I herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use the same.

This invention relates to improvements in dust-guards for j ournal-boxesor lubricatingreceptacles, and pertains more especially to an improveddust-guard having a body portion composed of two sections movableupwardly and downwardly, respectively, from within the journal boxwithout necessitating the removal of the box from the axle.

This invention consists in certain meritorious features of constructionand combinations of parts hereinafter described, and pointed out in theclaims.

In the accompanying drawings, Figure 1 is a side elevation, in centrallongitudinal section, of a journal-box provided with my improveddust-guard which is contained within the in ner end of the box andextends around the axle which extends into the box. Fig. 2 is a verticalsection on line 2 2, Fig. 1, looking in the direction indicated by thearrow. Fig. 3 is a top planin section on line 3 3, Fig. 2(

Fig. 8 is a top plan in section on line 8 8, Fig. 2.Fig. 9 is a top plan in section on line 9 9, Fig. 4. Figs. 3, 4, 5, 6,7, 8, and 9 are drawn on a larger scale than Figs. 1 and 2.

Referring to Figs. 1, 2, 3, and 4 of the drawings, a indicates ajournal-box, and b an axle which extends into the box in the usualmanner. The box is provided within its inner end with a quadrangularchamber 0, which extends around the axle and is occupied by acorrespondingly-shaped dustguard, which has a body portion comprising,preferably, an upper section D and a lower section (Z and is provided'with a centrally-located axle-accommodating circular opening 10, formedone half in the lower portion of the upper section D and the other halfin the upper portion of the lower section (1. The sections D and (1therefore embrace the upper portion and lower portion, respectively, ofthe axle b and meet each other at their adjacent ends at the sides ofthe axle centrally between the top and bottom of the axle. The sectionsD and (Z are preferably each composed of a sheet-metal plate. Theforward or outer side wall 12 of the chamber 0 is smooth and the forwardor outer side or face of the body portion (sections D and d) of thedust-guard is correspondingly smooth, so that whenthe said body portionis held against the said wall a dusttight joint is formed between thesaid wall and the body portion of the dust-guard. The chamber 0 is openat the top to accommodate the introduction thereinto of the uppersection D of the body portion of the dust-guard. The chamber 0 is openat the bottom of the j ournal-box to accommodate the introduction intothe said chamber of the lower section (1 of the body portion of thedust-guard. It will be observed, therefore, that the body por tion ofthe dust-guard is assembled relative to the axle by inserting the uppersection and lower section, respectively, of the said body portion at theupper end and lower end,respec tively, of the chamber 0. The twosections D and cl when they have been assembled rela tive to the axleare detachably secured together. The means preferably employed forseparably connecting the sections D and (Z together comprises twoupright metal bars G, arranged next to the rear side of the body portionof the dust-guard at opposite sides, respectively, of theaxle-accommodating opening 10. The two bars G are arranged verticallyand extend through correspondingly-arranged holes 13, (see Fig. 3,)formed in and extending through horizontally-arranged lugs or flanges14, with which the upper dust-guard section D is provided at its upperend, and cotter-pins f extend through the said bars next above the lugsor flanges 14.

The section D is provided a suitable distance above its lower end andadjacent to TOO each bar G with two lugs 16, which project from the saidsection D at opposite side edges, respectively, of the bar and overlapthat side of the said bar which faces the rear wall 15 of the chamber cthat is, two lugs 16 are formed upon the section D adjacent each bar Gand project from the said section at one side of the bar and form guidesfor the bar at opposite side edges, respectively, of the bar and projecttoward each other at and overlap I the section D at one side of the lugthrough the opposite side of the bar. The said lugs are instrumental inguiding the said bar during the assemblage of the parts and preventdisplacement of the said bar toward the rear side wall 15 of the chamber0.

Each bar G is provided near its lower end with two recesses g, formed inopposite side edges, respectively, of the bar, which recesses areengaged (see Figs. 2, 4, and 9) by laterallyfiexible lugs 17, formed inand projecting rearwardly from the lower section cl of the body portionof the dust-guard, which lugs also overlap that side of the said barwhich faces the rear side wall 15 of the chamber c that is, two lugs 17are formed upon the section d adjacent each bar G and project from thesaidsection at one side of the bar and snugly engage recesses g and g,formed in opposite side edges, respectively, ofthebar and project towardeach other at and overlap the opposite side of the bar.

By the construction and assemblage of parts hereinbefore described itwill be observed that the bars G are suspended and de tachable from theupper end of the upper section D of the body portion of the dustguardand detachably secured at their lower ends to the lower section (1 ofthe said body portion. The two sections D and d are therefore detachablyconnected together and obviously are free to be separated from eachother by withdrawing the cotter-pins f from the bars G.

The sections D and d are each provided with two springs 18, whichproject from opposite side edges, respectively, of the respectivesections and curve toward and into contact with the rear wall 15 of thechamber 0. The springs 18 are held under tension by the said wall 15 andact to retain the connected sections of the body portion of thedust-guard in engagement with the wall 12. The springs 18* operate,therefore, to maintain the dustguard in contact with the forward wall 12of the chamber 0. The opposing surfaces of the body portion of thedust-guard and the Wall 12 are smooth, and consequently the holding ofthe sections D and d in contact with the said wall insures themaintenance of a dusttight joint between the said wall and thebodyportion of the dust-guard. The upper section D of the body portionof the dustguard is provided at its rear side with an annular metalsection or bearing-piece K, extending circumferentially of the upperpore tion of'the opening 10 and aflording bearing tothe upper portion ofthe axle b. The bearing-piece K is detachably secured to the section D,and preferably the said member K is provided at the top and centrallywith an upwardly-projecting lug 20, which is provided with a slot orrecess 22, engaged, as shown in Figs. 1, 2,and 3, by a flexlble lip 23,formed on the'section D. The lip 23 projects from the recess 22 of thesaid lug and overlaps the opposite side of the said lug.

The bearing-piece K (see Figs. 2, 7, and 8) is provided also with twolaterally and outwardly projecting lugs 25, arranged at opposite ends,respectively, of the said bearingpiece. Each lug 25 is providedcentrally with a slot or recess 26, which is engaged by alaterally-flexible lip 27, formed on the section D. The lip 27 projectsfrom the section D at one side of the lug 25 of the bearing-piece Kthrough the recess 26 of the said lug and overlaps the opposite side ofthe said lug. The bearing-piece K can therefore be readily detached bybending the lugs 25 to render the said bearing-piece free to be removed.

An annular bearing-affording jaw L (see Figs. 1, 2, and 4) embraces thelower portion of the axle b and is shiftable vertically. The jaw Lextends circumferentially of the lower portion of the axle-accommodatingopening 10 and overlaps the rear side of the section (1 along the saidopening. The jaw L is provided with two vertical side edges Z, formed atthe opposite ends, respectively, of the jaw, which edges are overlappedby guide-forniing lugs 28, formed on and projecting from the lowersection (1 of the body portion of the dust-guard. The lugs 28 and edgesZ are instrumental in guiding the jaw L, which is held in contact withthe axle'by a suitablyapplied spiral spring Q, arranged centrallybetween the ends of and below the jaw and confined between the jaw and alug 30, formed on and projecting rearwardly from the lower end of thesection d. It will be observed, therefore, that the spring Q operatesnot only to retain the jaw L in contact with the axle, but acts also todepress the dust-guard and take up wear between the bearing-piece K andthe axle.
